Full preview and tutorial on how to get on the sandcrawler for the 2 datacrons without the 40 min long wait balloon. You need to be patient with the Jedi Knight due his Force Push would be in cooldown. Align yourself and you need to keep constantly jumping because of the angle when Jedi Knight Force Push you. So you fly upward 45' degree. After the successful landing, let the Jedi Knight Force Leap to you. Good luck! NOTE: Jedi Consular works as well with Force Wave BUT it only benefits 1 person. With a Jedi Knight, it benefits both.
